Bigger picture, Graham explained his reason for declaring "cap-and-trade is dead" is more about framing the debate for public consumption than anything else.

"This started with the planet is heating up and Iowa is going to become beachfront property," he said. "Now people go around not saying that much. I think they've oversold the consequences to climate change, to global warming. And the momentum around this large cap-and-trade bill to save the planet has been replaced by a business model: How do we create jobs and stay ahead of the Chinese and clean up the air? Once you start changing your perspective from 'Iowa is going to be beachfront property' to 'How do you create jobs and clean up the air?' you have a completely different focus."

He added, "We're going to fundamentally change how we price carbon looking at the economy differently than we have in the past. And the goal of this bill is not only to clean up the air but to create energy independence and jobs. The goal of cap and trade was to solve the Al Gore problem. I'm trying to solve the Lindsey Graham problem."

After interviewing Graham yesterday, Samuelsohn called me this morning, asking what I thought the motives behind this strategy might be and the possible impacts. Here's what I said:

Matt Nisbet, a professor of communications at American University, sees an opportunity for better public debate in the wake of Graham's comments declaring the end to the broad cap-and-trade approach.

"I think what's happening politically is we're moving from a very narrow limited focus on just one option," he said.

In the past, the longtime focus among politicians and reporters was on cap and trade alone, squeezing out other options like a carbon tax or a cap-and-dividend approach.

"Most of the discussion is not on substance, but rather political viability and the game or jockeying in order to win support," Nisbet said.

Nisbet said the single-tracked focus has soured the public's understanding of the legislative debate and all of its complexities. "What you have is a picture for the public of a lot of ideological crossfire from the left and right over a policy that very few members of the public understands, or even cares to understand," he said.

Looking forward, opponents will slap the "cap and tax" title on the bill no matter what sponsors say.

But he predicted that Graham's message about energy independence and jobs may be the right strategy, especially as he speaks to a different constituent group of independents and Southern voters, compared with some of the movement's traditional leaders.

"Even though they might share the same goals, Lindsey Graham, Al Gore and John Kerry, they're also trying to differentiate among themselves and claim credit for achieving those goals," Nisbet said.
